After its earlier confirmation of the Premium Suite upgrade for its first generation Galaxy Note, Samsung has now posted the first service manual based on Android 4.1.2 (Jelly Bean) for the device. Although the rollout date for the software upgrade is yet to be confirmed, it is expected soon.

Until then, Galaxy Note users can experience Jelly Bean features through custom ROMs. Recently XDA developer, neobuddy89, released a custom build named as Stunner 2 (v2.1.27) for the Galaxy Note with model number N7000. The custom firmware is based on the latest Android 4.2.1 (Jelly Bean). One of the key features of the Stunner ROM is that it is built from both AOKP and CyanogenMod (CM) sources.

"Stunner 2 is built from AOKP/CM sources merged for features and performance and always carries a very light installation with no extra/useless apps. This means, you can enjoy a pure Android experience combined with AOKP/CM features and some CM cherry-picks. Keep in mind Jelly Bean is only at the beginning stage of development and there will be minor bugs," says the developer.

Galaxy Note users who wish to update their devices with Stunner Android 4.2.1 Jelly Bean ROM may follow the guide below. IBTimes UK reminds its readers that it will not be held responsible for any damage to the device. Users are advised to verify the model number of the phones since the aforementioned Jelly Bean ROM works only with Samsung Galaxy Note N7000, not with any other variants.
